Spring-Lock
Spring-Lock is a sealing lip feature that
surrounds 270° of the garter spring’s diameter
(fig 69). The Spring-Lock helps hold the spring
in position during seal handling, installation and
removal. It is standard on all HDS and HS
seals.
Spring-Kover
In applications where dirt, water or other
contaminants may pose serious problems or
where installation could jar the spring out of
place, Spring-Kover can be specified. Spring-
Kover is a flexible covering over the exposed
portion of the stainless steel garter spring
(fig 70). It protects the spring without
adversely affecting the spring’s capability.
Spring-Kover is available on all seals except
HS3.
Bore-Tite ®
Bore-Tite is a water based acrylate sealant
that is an option available on most SKF metal
clad seals. The sealant is used as a coating on
the outside diameter of the seal (fig 71). The
Bore-Tite layer is pliable with a thickness of
0,03 to 0,07 mm (0.0012 to 0.0028 in),
allowing the sealant to help fill small
imperfections in the housing bore. Bore-Tite
can be used at temperatures up to 200 °C and
is compatible with most oils, greases, aqueous
acids and alkalis, alcohols and glycols. Please
note that Bore-Tite is not compatible with
aromatics, ketones and esters. Incidental
contact with these substances will have little to
no effect if wiped off quickly.
